RAIL TIE AND CHAIR.

Specification of Letters Patent.

Patented Nov. 13, 1906.

To all whom it may concern:

Be it known that I, ERNEST BUTLER, a citizen of the United States, residing at Man kato, in the county of Blue Earth and State of Minnesota, have invented certain new and useful Improvements in Rail Ties and Chairs;

and I do declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains -to make and use the same.

My invention is an improved railroad-tie and rail-chair and it consists in the construction, combination, and arrangement of devices hereinafter described and claimed.

The object of my invention is to provide a metallic railroad-tie of novel construction which is exceedingly strong and durable and is formed or provided with devices which serve to secure the rails on the tie and prevent the possibility of their spreading, while enabling the rails to be readily taken up and replaced when they have become worn or broken.

In the accompanying drawings, Figure 1 is partly an elevation and partly a sectional view of a railway tie and chair embodying my invention. Fig. 2 is a top plan view of the same; and Fig. 3 is a transverse sectional view of the same, taken on the plane indicated by the line a a of Fig. 17

My improved railway-tie 1 is made of iron or other suitable metal, is of oblong rectangular form in cross-section, and is provided with a hollow or core 2, which extends therethrough from end to end to reduce the Weight to effect a corresponding economy in the construction of the tie and to also form a clearancespace for the hooks of the detachable knees of the chairs hereinafter described. The tie is formed with fixed knees 3 on its upper side, adapted to engage the base-flanges on one side of the rails at a suitable distance from the said knees 3, and on the opposite sides of the rails the tie is formed with up standing lugs 4. Slots 5 are also formed in the upper side of the tie between the fixed knees 3 and the lugs 4. I also provide detachable knees 6 to bear against and engage the base-flanges of the rails on the sides opposite those engaged by the fixed knees 3. Each of the said detachable knees is provided with an opening 7 to receive one of the lugs 4:, the said lugs acting to prevent the said knees 6 from being moved outwardly, and hence preventing the rails from spreading. Each detachable knee is provided on its under side at its inner end with a depending hook 8 to extend down through one of the openings 5 in the tie and to bear under the top of the tie to prevent the inner ends of the said detachable knees from being raised, said hooks 8 thereby coacting with said knees 6 and the upper side of the tie to securely lock the rails on the tie. Bolts 9 are passed through alined openings in the lugs 4 and detachable knees 6 to secure the latter on the tie and adapt them to readily detach therefrom when required.

From the foregoing description, taken in connection with the accompanyingdrawings, the construction, operation, and advantages of the invention willbe readily understood Without requiring a more extended explana tion.

Various changes in the form, proportion, andthe minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined by the appended claims.

Having thus described my invention, wha I claim as new, and desire to secure by Letters Patent, is

1. A tie having a fixed knee on its upper side to engage one side of a rail, an upstanding lug opposite the other side of the rail, and a slot in its upper side between said lug and the rail, in combination with a detachable knee to engage the rail having an opening to receive the said lug and provided on its under side with a hook to engage a shoulder formed in the upper side of the tie, substantially as described.

2. A tie having a fixed knee and a fixed lug on its upper side appropriately spaced apart and further provided withalongitudinalbore and with a slot in its upper side between said lug and fixed knee and communicating with said bore, in combination with a detachable I In testimony whereof I have hereunto set v knee having an opening to receive the lug my hand in presence of two subscribing witand provlded on its under side with a hook: nesses.
